  • the static charge may preferably be applied across the entire width of the web or webs.
  • the extrusion coating itself may be used to temporarily join the webs 10, 12 along one or more edges.
  • the extrudate then tacks down the webs 10, 12 along the unaligned edge or edges.

  • the temporarily joined webs are referred to collectively as the "composite web"32.
  • the first web 10 be coated in the first extrusion station as a single web. Thereafter the second web 12 may be laid on to the first web 10 prior to entering the second extrusion station. In this manner, the second web 12 as well as the first web 10 may be unwound coating side up, thereby eliminating the need to invert the webs after the first extrusion station.
  • first and second webs 10, 12 may be extrusion coated separately and thenjoined prior to being wound up together.
  • the webs may be would up separately without ever being joined together using dual windup stands at the end of the multi-station extruder.
  • first and second webs 10, 12 be temporarily joined as shown in Fig. 2 because this facilities collecting both finished webs on a single windup stand for later separation using a rewinder.

  • the second polymer melt is also extruded at a feed rate of about 226.8 kg/h (500 lb/ h) to about 453.6 kg/h (1000 lb/h) while the web is conveyed at a speed of about 228.6 m/min (750 ft/min) to about 457.2 m/min (1500 feet / min) to provide a polymer coating 52 having a thickness of about 0.0127 mm (0.5 mils).

  • the webs 10, 12 may be separated from one another in line as seen in Fig. 5 and collected on separate wind up rolls directly after the second extrusion coating.
  • the first and second webs 10, 12 be initially wound up together as a composite roll 54.
  • the webs are preferably temporarily joined together, typically along the edges of the webs 10, 12.
  • the composite roll 54 may then be processed on a rewinder apparatus 80, shown in Fig. 7, which includes a trimmer 82 which cuts away the joined edges thereby separating the finished webs and allowing the webs 10,12 to be individually wound up on two separate windup rolls 84; 86.
  • a dual or tandem station extruder may be used to approach or fulfill its rated capacity while applying one-side only coatings to substrate webs.
  • the method allows the production speed of a dual extruder to be effectively doubled when used for one-side only coatings since two such products may now be extrusion-coated at once.
  • the two substrates and their respective coatings may be the same.
  • the invention may thus be used to dramatically increase the rate of production of a single type of extrusion coated substrate.
  • the substrates and / or their polymer coating may also different.
  • the invention provides a means to produce small batches of relatively low-volume coated substrate without halting production of much larger batches of a higher selling-volume product.
